I think this misinterprets some of the concern about Berrios. It is not so much that he is short but that he is relatively mature already which limits his future physical projection. This, combined with an advanced pitchability for a high schooler, led many scouts to project that he would be very effective at lower levels but with less of a ceiling. The upshot is that he might be able to move faster than a typical high school arm but that his ceiling would be lower than what might be expected based on numbers he puts up in the lower levels. I like the pick, I like Berrios as a prospect, and I hope that the Twins are more aggressive with him than they might otherwise be with a high school arm. I would be surprised if he is a top 5 Twins prospect going into next year - I would assume/hope Sano, Buxton, Rosario, Meyer, and the #1 pick would all be higher.
